Abstract |
This study aimed to investigate salinity's impact on the germination process and the
metabolic profile of germinated seedlings in three rice cultivars known for their varying levels
of salinity tolerance. The seeds of three rice cultivars, KDML105 (salt-sensitive), IR29 (saltsensitive), and Pokkali (salt-tolerant), were germinated in two different treatments: distilled
water and a 40 mM NaCl solution. Salinity delayed seed germination and caused root shape
abnormalities. The root length of all cultivars was significantly decreased by salinity; however,
Pokkali showed the highest root length among these cultivars. Salinity also decreased total
soluble sugar, glucose, and fructose content, while starch content was unaffected. Na+
/K+
ratio
in root and shoot was significantly increased in all cultivars; however, the increase was much
lower in the tolerance cultivar. Metabolic profiles revealed several biomarkers of the salt stress
response among cultivars and between the control and stressed groups. Gamma-aminobutyric
acid was increased in all cultivars. Citric acid, L-lysine, and L-valine were reduced, while uracil
was increased in KDML105. L-lysine, succinic acid, and L-methionine were decreased, while
adenine was increased in IR29. Oxalacetic acid, L-proline, and urea increased while melatonin
decreased in Pokkali. |
